Using PVR-350 to record old VCR video

I've long since removed my PVR-350 from the config of the system -- (ComCast no longer does "analog" ) but would like to transfer some old VCR tapes to .mpg format.

I'm assuming once I pull the PVR-350 out of the config files, mythtv should no longer try to fuss with it.

If that's the case, when I used mplayer to try and tune to CH:3 and copy the stream to disk, the commandline just sits at "Cache Fill" -- and I can't seem to (for the life of me) set the darn format using "normid=0" to NTSC.

oh, and before I forget, my VCR is on Channel:3 on the RF output... and I've verified this against an older LCD monitor from Samsung that's also a TV. (the video doesn't look awesome, but that's the age of the tape and the original crappy OTA setup)

Any reason not to use the SVideo output instead? The VHS is going to look like crap regardless, but no sense making it worse by using the cheap modulator on the VCR. _______________________________________________ mythtv-users mailing list mythtv-users [at] mythtv http://www.mythtv.org/mailman/listinfo/mythtv-users

"config files"?

You need to go into mythtv-setup, Capture Cards section, then select the PVR-350 device(s) and hit DELETE (by default 'D' key) to delete the cards from MythTV's configuration.

My PVR150 has a composite in and I simply use cat /dev/video0 >file.mpeg, after setting the inputs correctly with v4l2-ctl _______________________________________________ mythtv-users mailing list mythtv-users [at] mythtv http://www.mythtv.org/mailman/listinfo/mythtv-users

Did that -- I get a 0byte length file.

In other news, if I put the composite video on the pcHDTV-5500 card (I have 2, both do the same thing) - I get pretty bad video... but on the tuner of the pcHDTV, I do get video that looks pretty close to the original format minus the conversion from the capture format of the card to what mencoder dumps out.. (which looks to require a lot of tweaking)

but once I go back to trying the PVR-350... mencoder either complains it can't open the demuxer or mplayer just sits at that same deal.

v4l2-ctl let's me to stuff to the card, but it doesn't help. (although --log-status shows some interesting stuff... )

Thanks for the help though - I can see Myth isn't trying to commandeer the card anyway. (and I shut down the backend just to be sure anyway)

run the script with "record 1" and it will record one minute of video from the desired input.

This is the script I used a couple of years back to record old home videos via my PVR-250. I use the SVideo input (1), but if you want to use composite, just use "v4l2-ctl -i 2". If you need to use the RF tuner use "v4l-ctl -i 0" and you'll also need to set the frequency using "v4l2-ctl -f FREQUENCY".

What I did was leave it in the configuration, but set the composite input to connected to a dummy listing that only has channel 1, which I named "VCR." Now I can do manual recording through Myth from the VCR, which works better for me than doing it outside Myth.

I noted that my PVR-250 claims to have three composite inputs, which I suspect are actually separate chroma and luminance, along with the full composite, as one is junk and the other is black-and-white. Be sure you select the correct input. _______________________________________________ mythtv-users mailing list mythtv-users [at] mythtv http://www.mythtv.org/mailman/listinfo/mythtv-users

I'm not sure what use this would be, as there is still only one decoder on board, shared by everything. Perhaps ancient video editing suites.
